Anil Kumar Gupta, Amarjeet Kumar Sharma, Aditi Pandey, Patil Kaustubh, Sanskar Sharma · 2022
In the wake of digitalization, the need for highly efficient and available application programs is increasing. Hence arises the need for better resource utilization, fault tolerance and, process optimization approaches to make reliable and secure systems. A possible solution to the given problem is proposed in the live migration. The chapter starts with giving a brief overview of live migration and then proceeds with discussing two of the live migration approaches - live virtual machine(VM) migration and live container migration. Starting with live VM migration, the performance metrics concerning live migration along with various live VM migration techniques are explained. Next, it discusses the challenges in this approach and then reviews the security aspects associated with it. Then the chapter turns over to the second approach, live container migration. It begins with explaining different types of migration techniques and various case studies of implementation. This is then followed by understanding the performance measures and issues and then does a fair comparison between the two methods. Finally, the chapter concludes with the discussion on the various security problems and then gives its solution to take a step towards protection.
